Hello all. I live in South Florida. I m looking for a generator for potential hurricane power outage. I've consulted several calculators. It seems I need about 4000 running watts. Do I get double the running watts. Do I get one that only covers running watts with some extra for surge. I'm confused. Just want to make sure my fridge.. some fans.. tvs run. I'm thinking 5500 watts. My brother says 7500 watts. My dad says 10000 watts. Can I run everything off 1 10 gauge cord or several cords.
